London , England -LRB- CNN -RRB- -- The pressure on Inter boss Rafa Benitez intensified on Sunday as his team crashed to a 2-1 defeat to Chievo in Serie A.

To compound the issue , star striker Samuel Eto'o looks likely to receive a retrospective ban after television cameras showed him head-butting opponent Bostjan Cesar in the chest late in the first half .

The referee and officials missed the incident , which was reminiscent of Zinedine Zidane 's head-butt on Marco Materazzi in the 2006 World Cup final in Germany , but if reported the Cameroon international is likely to be sidelined for several matches .

Chievo took the lead shortly before the Eto'o incident , when Sergio Pellissier headed home after 29 minutes .

And the home side made sure of victory eight minutes from time when substitute Davide Moscardelli tucked away a cross from Luca Rigoni .

Eto'o scored a brilliant individual goal in injury time but it was too little , too late .

`` It 's clear that after a defeat no-one is happy , the only thing I can say is that we worked very hard today and our reaction in the second half on a terrible pitch showed great character , '' Benitez said , AFP reported .

The result means his team is now in sixth place , nine points adrift of leaders and city rivals AC Milan .
